Osnos was actually interviewing various Dissident Right types for a completely different article about the Dylann Roof shooting, and the last-minute editorial change of direction is painfully apparent. Trump apparently barely came up in Osnos' questioning, and anyway his subjects did not pretend to know Trump or anything much about him.
VDARE.com (which Osnos did not contact) and an article by James Kirkpatrick make a cameo appearance:
Ordinarily, the white-nationalist Web sites mock Republicans as Zionist stooges and corporate puppets who have opened the borders in order to keep wages low. But, on July 9th, VDARE, an opinion site founded to “push back the plans of pro-Amnesty/Immigration Surge politicians, ethnic activists and corrupt Big Business,” hailed Trump as “the first figure with the financial, cultural, and economic resources to openly defy elite consensus. If he can mobilize Republicans behind him and make a credible run for the Presidency, he can create a whole new media environment for patriots to openly speak their mind without fear of losing their jobs.” The piece was headlined “WE ARE ALL DONALD TRUMP NOW.”(The New Yorker doesn't do hyperlinks, so I've added them to the relevant sections of VDARE.com).
Maybe the New Yorker's much-lauded fact-checking department is responsible for the fact that VDARE.com is, for once, not labelled as "White Nationalist." On the other hand, it let Osnos get away with the Treason Lobby factoid that "the crime rate among first-generation immigrants is lower than that for native-born Americans," despite its definitive refutation by Ann Coulter.
